Application December 10, 1954, Serial No. 474,398

. l'Claim. (Cl. 160-180) This invention relates to a window screen and,more particularly, to a window screen for casement-type windows. i

An object of this invention is the provision of a window screen having apassageway defined by the frame thereof and which passageway makes itpossible to operate a window latch interposed between the screen and awindow covered by the screen.

As an additional object this invention aims to provid a window screenwhich is unusually attractive in appearance. a

A further and important object is the provision of a durable windowscreen which employs a minimum number of structural parts, is light inweight, and economical to manufacture.

Other more particular objects and advantages will, together with thesegeneral objects, appear and be understood in the course of the followingdescription and claims, the invention consisting in the novelconstruction and in the adaptation and combination of parts hereinafterdescribed and claimed.

In the accompanying drawings:

Patented Nov. 18, 1958 hardware. In the conventional window screenprovision for this movable part is attained by having a strike at- Fig.3 is an enlarged-scale fragmentary view shown partly in elevation andpartly in section to detail the intersection between a brace and a framechannel employed in the present invention.

Fig. 4 is a detail sectional view taken on line 44 of Fig. 3.

Fig. 5 is a fragmentary transverse vertical section drawn to an enlargedscale on line 55 of Fig. 1; and

Fig. 6 is a fragmentary view shown partly in elevation and partly insection to detail the joinder of the channel pieces employed in theframe and strike.

In many of the popular casement type windows the window is divided intoa stationary and permanently closed section and a movable section whichis adapted to be opened. Inasmuch as the movable section of the windowusually opens outwardly and away from the casement, a window screen,when employed, is mounted on the inside of the casement. Theaccessories, such as a cam latch or a casement-type latch, for use inopening and closing the window are also on the inside of the casementand, of necessity, are interposed between the screen and the window. Asthese accessories are comparatively large and protrude inwardly of thewindow provison must be made for that part of the screen 'adjacent tothe accessories to clear the same and also for working said windowhardware. Both of these provisions are usually taken care of by makingthe screen, similarly to the window, in two sections, a stationarysection and a movable section with the movable section raised inwardlyof the stationary section so as to clear the window tached to the frameof the screen and which strike outlines an access opening through thescreen for working the Window attachments. This access opening isnormally closed by the movable part of the screen. As contrasted withthis conventional screen in which the strike is added to the frame, inmy presently utilized screen the strike is part of the frame and alsodefines a passageway giving access for the working of the windowaccessories.

Proceeding now to describe the invention, it is seen that referencenumeral 10 denotes a window screen having a relatively large stationaryarea 11 and in comparison therewith a relatively small movable area,namely, wicket 12. The screen, as common to most screens, comprises aframe 13, but unlike other screens includes the novel feature that itsstrike 14 is also an integral part of the frame and not a mere additionthereto. The frame is produced from channel stock with the majority ofsaid frame straight channel, while the strike portion of such frame iscurved to the approximate configuration of a half-circle. Said strike,as herein shown, is spaced equidistantly between the ends of the framealong one side and bends inwardly of the frame toward the other sidethereof.

The channel stock is composed of sheet metal, aluminum by preference,which has been rolled to form a tube 15 and a channel 16, with both thetube and the channel extending longitudinally of the stock. In atransverse cross-sectional view of the channel stock the channel is ofan approximate U-configuration so disposed that the throat thereof isexposed to a side of the stock and the tube is substantially a squarewith the exception that there is provided a connecting groove 19underlying the base of the channel.

The individual channel stock pieces, both the straight sections and thecurved strike, are joined by braces 17. These braces, as illustrated,are right angle members and are a stamping comprising a major leg 26 anda minor leg 27 with the two legs lying substantially at right angles toeach other. The ends of the legs are cut on the bias, and the portions28 of the major leg are caused to be bent upwardly substantiallyparallel with the minor leg so as to define a minor channeltherebetween.

In preparing the individual frame members for assemblage the ends ofeach member are cut at a 45 angle so that there is a miter joint at thejuncture of adjacent members. The individual members are assembled intothe frame with the channel running around the inside of the frame byinserting the braces into the end openings of the tube portions sothat-the outside edge of the braces major leg rides in the groove 19adjacent to the channel and the legs of the minor channel formed by thebrace press firmly against the opposite walls of the tube so that thescreen will be rigid.

After the individual frame members have been tightly pressed togetherthe frame is ready to receive a section of screen mesh 18. A precut meshis applied to the frame by laying the same on the frame with theperipheral edges thereof overlying the channels. Then a tube 20 or rodof flexible material such as aluminum or plastic is forced, along withthe screen mesh, into the channel. The walls of the channel yieldsomewhat to accommodate the screen mesh and tube so that the two arefirmly held in the channel by a spring grip.

The passageway in the window screen formed by the strike is covered bythe wicket. This wicket comprises a section of screen mesh 21 whoseedges are protected by strip metal 22 which has been rolled to have adeep narrow groove, and is held onto the mesh by crimping the sheetmetal over the edges of the same. This wicket is swingably mounted by aspring-loaded piano hinge fastened to the frame by screws 29. As thereis an opening at that part of the screen between the outer edge of thewicket and the side of the frame where the strike is I prefer that thestationary or butt leg 24 of the piano hinge be of approximately thesame depth as the channel so as to effectively cover said opening,making it impossible for flies and the like to pass therethrough.

The strike, in addition to defining a passageway through the screen,also serves the function of spacing the wicket farther away from thewindow than the stationary part of the screen, and in this manner thewicket is assured of clearing window accessories interposed between theg screen and the window.

The screen is attached to the casement by a bracket 25 comprising anL-shaped member having a long leg and a short leg. The long leg clampsover the frame and the short leg bears by its edge against the easement,illustrated by broken lines in the drawings. Said bracket is attached tothe casement by a screw 30.

The advantages of the invention, it is thought, will have been clearlyunderstood from the foregoing detailed description of the illustratedpreferred embodiment. Minor changes will suggest themselves and may beresorted to without departing from the spirit of the invention,wherefore it is my intention that no limitations be implied and that thehereto annexed claims be given a scope fully commensurate with thebroadest interpretation to which the employed language admits.

In a window screen, a generally rectangular border frame providing acontinuous border channel and modified from a rectangle by a re-entrantportion which forms an entry and has one of its faces for a wicketstrike, a screen covering the opening defined by said frame and havingits margin in said channel, rod means within said channel for retainingsaid margin of the screen therein, a hinge member spanning the mouth ofsaid entry with co-planar portions projecting at each end therebeyondand having said end portions overlying and removably secured by screwsto the border frame adjacent the ends of the re-entrant portion, awicket hingedly connected to said hinge member, said wicket comprising awicket screen for covering said entry and a wicket frame gripping themargin of said wicket screen, and spring means yieldingly urging saidwicket frame into contact with said wicket strike.
